1. Business requirements
With the development of modernization, the ownership of special vehicles such as tank trucks, hazardous chemical trucks, dump trucks, city buses, taxis, military police vehicles, etc. has also continued to increase. Traditional special vehicle management The model has been unable to meet actual needs, the efficiency of supervision is low, and there are hidden safety hazards.
The special vehicle positioning and identification information management system adopts a variety of information technology fusion solutions, installs the “VID-S2 radio frequency identification card” on the vehicle, and uploads the GPS information to the background server through the GPRS wireless communication module to realize the management and scheduling of the vehicle ; At the same time, you can also use the “VID-R2 handheld radio frequency reader” to detect the UHF in the radio frequency identification cardelectronic labelCarry out long-distance reading, and implement vehicle verification and inspection.
Second, the system architecture
The structure of the special vehicle positioning and identification information management system is shown in Figure 2A.Reader”And the back-end server. Among them, the radio frequency identification card is installed on the windshield of the vehicle to receive GPS satellite information, obtain the current location data, access the Internet through the GPRS network, and send the vehicle location information to the back-end server, using a handheld radio frequency The reader can also perform effective inspection and management of vehicles. According to the different needs of the application field and industry, the system software running in the back-end server can provide vehicle management and real-time monitoring functions including information such as the unit, license plate number, driver, etc. .
Three, application process
For special vehicles, the VID-S2 radio frequency identification card will be issued after registration and approval, and be applied to each vehicle. The radio frequency identification card corresponds to the vehicle one-to-one, and the license plate number plate is stored in the form of encrypted data. Information about the department that the vehicle belongs to, the area where the vehicle is permitted to pass, and so on.
Dingshi “VID-R2 handheld radio frequency reader” is equipped with road site inspectors to implement non-stop verification for special vehicles.
Fourth, the software module
Special vehicle positioning and identification information management system software modules.
Five, system characteristics
1. Integrate radio frequency identification (RFID), global positioning system (GPS), general packet radio service (GPRS), geographic information system (GIS), multimedia, database, network communication technology and other IT technologies to achieve the integration of multiple information technologies.
2. Real-time control of the operating status of each vehicle, including location, direction, vehicle speed, and display of vehicle trajectory, which can facilitate vehicle scheduling. When danger occurs, it can guide the tracking and disposal of rescue vehicles, and supervise driver violations by the management department Provide effective technical means such as car use, speeding, fatigue driving, and improving the level of vehicle dispatching.
3. It has a special management plan for security and confidentiality, shielding or strictly controlling the traffic synthesis of confidential vehicles and confidential mission vehicles, the transmission of information adopts an encryption method, and the key is safe and reliable.
